Abstract

The purpose of this research was to improve network speed and security in a lecture hall using the Control Objectives for Information and Related Technologies (COBIT) 2019 methodology and to design a well-standardized Fiber to the Home (FTTH) network. Data collection was conducted by sending a COBIT 19 capability-level questionnaire to the Information Systems Department (DSI) and students. The questionnaire assessment to the DSI resulted in a capability level of 4 (final score for BAI03 62%, DSS05 32%), and a maturity level of 3. The student questionnaire assessment resulted in a capability level of 1 for the BAI03 subdomain, with a final score of 78%, with a maturity level of 0. A capability level of 2 was achieved for the DSS05 subdomain, with a final score of 36%, with a maturity level of 1. The questionnaire assessment generated several recommendations and solutions for improvement. Several solutions from the COBIT 19 questionnaire assessment were used as guidelines in FTTH network design, aimed at meeting user needs. Researchers collected design data through direct observation at the research site. The network design was tested using two testing methods: manual formula calculations and OptiSystem testing. The manual formula calculations yielded an average attenuation value of -34.26 dBm. The OptiSystem tests yielded an average attenuation value of -41.20 dBm. These design results successfully improved network speed, with an attenuation value that surpasses the current network's attenuation of -46 dBm.
